Teorías Hipótesis verificadas repetidamente. n Se pueden descartar con el paso del tiempo a la luz del nuevo conocimiento. n n Ej. La abiogénesis
Science is a Human Endeavor 4. 5. Fleming hypothesized that the mold produced an antibacterial substance Further tests using broth from pure Penicillium cultures lead to the discovery of the first antibiotic, penicillin
Science Is Based on Reasoning n Inductive Reasoning Used in the development of scientific theories n A generalization is created from many observations n e. g. , the cell theory (all living things are made of one or more cells) arises from many observations that all indicate a cellular basis for life n
The Scientific Method Scientific experimentation tests the assertion that a single variable causes a particular observation n The experiment must rule out the influence of other possible variables on the recorded observations n
The Scientific Method Controls are incorporated into experiments n Controls keep untested variables constant n Scientific method is illustrated by Francesco Redi’s experiment n
